Description

human sensor light

technical field

The utility model relates to a lighting fixture, in particular to a human body induction lamp, which is suitable for use in corridors, corridors and public places.

Background technique

In order to save energy, the lights installed on the stair walkway can usually be turned on and off automatically. The control methods for turning on and off the lights often include voice control, human body induction and other methods, so that the lights can be turned on when people come and go, and no human operation is required. . However, some lamps often have problems such as unstable performance and poor sensitivity due to their unreasonable structural design, so they need to be further improved in structure.

Contents of the invention

The technical problem to be solved by the utility model is to provide a human body induction lamp with reasonable structure, convenient use, stable performance and good sensitivity in view of the current state of the art.

Detailed ways

The utility model invention is further described in detail below in conjunction with the accompanying drawings.

As shown in the figure, the lamp housing of the induction lamp can be in various shapes such as square, round, or rectangular. It includes a cover 1 and a bottom plate 8 that are covered with each other. There is an opening 11 on the top of the cover 1. The opening The shape is not limited, and the lamp 4 and the pyroelectric induction head 3 are arranged at the opening 11 . A fixed plate 12 matching the shape of the opening is fixed in the cover 1, the lamp 3 and the pyroelectric induction head 4 are installed on the fixed plate 12, and a transparent lampshade 2 is covered on the fixed plate 12, and the lampshade 2 is placed on the fixed plate 12. The part corresponding to the lamp is a convex arc surface, and the part corresponding to the pyroelectric induction head has a sensing window.

The pyroelectric human body sensor includes the pyroelectric sensor head 3 and the signal processing circuit board 5, the pyroelectric sensor head 3 is composed of a Fresnel lens and a pyroelectric infrared sensor, and the pyroelectric infrared sensor is installed Inside the plastic case behind the Fresnel lens, the Fresnel lens is located at the sensing window. The lamp 3 adopts several LEDs, and the LEDs and the pyroelectric infrared sensor are electrically connected with the battery and the signal processing circuit board 5 located inside the cover. A cover plate 6 is also fixed below the signal processing circuit board 5, and a magnetic block 7 is respectively embedded on the four corners of the cover plate 6, and a magnetic block 9 is also provided on the base plate 8 correspondingly, so that the base plate 8 passes through The magnetism is firmly attracted to the cover plate 6, so that the bottom plate 8 and the cover 1 are closed together, which simplifies the assembly of the product and facilitates the replacement of the internal battery.

And in order to facilitate the use of the lamp, the bottom of the base plate 8 is pasted with double-sided adhesive tape 10, and this induction lamp can be fixed on the appropriate position on the wall by this double-sided adhesive tape 10, which is convenient to use.

This induction lamp uses the detection of changes in the infrared radiation temperature of the human body to focus on the pyroelectric element through the Fresnel lens. Once someone enters the sensing area, the lamp will automatically light up immediately. When moving again, the light will be automatically turned off after a certain delay, and its working distance and delay time can be set according to needs.
